Description
Lincoln Industrial rotary 24 V
electric pump uses a 24 V
motor and
either a single or two stage planetary gear
drive. Grease output is proportional to pump
revolutions per minute. Pump is primarily
designed for centralized lubrication systems
such as single line parallel, single line
progressive and two line systems.
Pump is driven by rotary motion of
electric motor. Rotary motion is converted to
reciprocating motion through eccentric crank
mechanism. Reciprocating action causes
pump cylinder to move up and down. Unit is
a positive displacement double-acting pump
as grease output occurs during both up and
down stroke. Pump motor employs an
integral speed control capable of reducing
pump speed to 10% maximum value.
During down stroke, pump cylinder is
extended into grease. Through combination
of shovel action and vacuum generated in
pump cylinder chamber, grease is forced into
pump cylinder. Simultaneously, grease is
discharged through outlet of pump. Volume
of grease during intake is twice amount of
grease output during one cycle.
During upstroke, inlet check closes, and
one half of grease taken in during previous
stroke is transferred through outlet check
and discharged to outlet port. Typical output
of pump is shown in
Table 2

Inspection
If overpressurizing of equipment is believed
to have occurred, contact factory authorized
warranty and nearest service center for
inspection of pump.
Specialized equipment and knowledge is
required for repair of pump.
Annual inspection by factory authorized
warranty and nearest service center is
recommended.
Damaged Pumps
Do not use any pump that appears to be
damaged, badly worn or operating
abnormally. Remove pump from service and
contact factory authorized warranty and
nearest service center for repairs.
Listing of authorized warranty and service
centers is available upon request.
Overview
This manual details the procedure that must
be followed while installing, operating,
troubleshooting and repairing FlowMaster II
rotary driven 24 V
electric pump.
All required parts, tools, and equipment
needed to complete operation of
FlowMaster II rotary driven 24 V
electric
pump are defined and listed within manual.
Review of parts list and nomenclature is
recommended before starting disassembly
or operation.
Appropriate use
All pump models are exclusively designed to
pump and dispense lubricants using electric
power. Specifications for pump are shown in
Table 1
. Maximum specification ratings
should not be exceeded.
Any other use not in accordance with
instructions will result in loss of claims for
warranty and liability.
1)
Motor controller will shut motor off when outside of voltage limits.
Test conducted with Alvania NLGI 2 grade grease at 1 000 psi
(68 bar)
backpressure.
